An aircraft wing level measuring device that is easy to disassemble

Abstract

The invention relates to an aircraft wing level measuring device that is easy to disassemble and assemble, comprising a fixed base, a magnet block is embedded in the lower part of the fixed base, a threaded groove is arranged on the upper part of the fixed base, a rotating table is fixedly connected inside, and a rotating table is fixedly connected on the top of the rotating table. Mounting plate, the middle part of the mounting plate has a placement slot, the lower part of the mounting plate is sleeved with a pin shaft, the level is mounted on the pin shaft and can rotate around it, one side of the front end of the mounting plate is hinged with a card plate, and the other side is fixed with a card slot , the card board is placed in the card slot to ensure that the level does not rotate out of the placement slot when it is not measuring; Find the horizontal position of the level ruler accurately under the ruler. The device of the present invention is convenient to assemble and disassemble, has good flexibility and is convenient to store and use.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to an aircraft wing level measuring device which is easy to assemble and disassemble. Background technique [0002] The level measurement of the aircraft refers to the measurement of the relative position accuracy of the various components of the aircraft when the aircraft is in a horizontal state. The accuracy of the relative position between components mainly includes the anhedral angle of the wing and empennage relative to the fuselage, the accuracy of the installation angle and the sweep angle, the deflection angle, fit, and fit clearance of each movable wing surface relative to the fixed wing surface The accuracy is worse than that of scissors, and the coaxiality of each section of the fuselage. [0003] At present, the domestic aircraft level measurement work adopts the sub-item level measurement method, mainly adopts the level measurement method based o...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic aircraft level measurement work adopts the sub-item level measurement method, mainly adopts the level measurement method based on optical theodolite, and compares the difference between the measurement points in the direction of the fuselage coordinate axis with the theoretical value on the aircraft level measurement chart to check Whether the installation between the various parts of the aircraft meets the requirements, whether the geometric dimensions of each profile are within the limited range, but the level measurement based on the optical theodolite mainly has the disadvantages of inconvenient disassembly and assembly of the transfer tool, small measurement range and inconvenient use
